Living in Arizona with a furry friend can be a wonderful experience, but it's essential to be aware of the unique health risks our desert climate poses to dogs. Arizona's hot and dry weather can be challenging for dogs, especially those with certain health conditions.
Dogs in Arizona are at a higher risk of contracting diseases like Ehrlichiosis and Anaplasmosis, which are transmitted through tick bites. These diseases can cause symptoms such as fever, lethargy, and loss of appetite.
The Arizona desert heat can also exacerbate conditions like heatstroke, which can be life-threatening if left untreated. This is especially true for dogs with thick coats or those that are not accustomed to the heat.
Dogs in Arizona should be protected from the sun and heat by providing shade, plenty of water, and regular breaks during outdoor activities.

Causes and Prevention
Dogs in Arizona are at risk of contracting various diseases, and understanding the causes and prevention methods can help protect their health.
Coccidioides organisms live in desert soils and produce long filaments of mold that contain infectious spores.
If you live in a Valley Fever endemic area, such as Pima, Pinal, or Maricopa counties in Arizona, take steps to protect your dog's health by reducing their exposure to soils and airborne dust. Keep your dog indoors as much as is practical, and when outside, keep them on a leash and walk them on paved sidewalks.
Dogs can also develop leptospirosis, a bacterial disease, through exposure to wild animals or farm animal species that may pass infected urine, even in your backyard. Contact with rodents, such as squirrels or rats, or other dogs can also increase their risk.
Here are some factors that can increase your pet's risk of leptospirosis:
- Exposure to wild animals or farm animal species that may pass infected urine, even in your backyard
- Exposure to or drinking from streams, lakes, rivers, or puddles
- Contact with rodents, such as squirrels or rats, or other dogs (such as in dog parks, facilities where multiple dogs are housed, or urban areas)
What Causes?
Coccidiodes organisms live in desert soils and produce long filaments of mold that contain infectious spores.
These spores become airborne when the soil is disturbed, such as by a digging dog, by construction, or during a windstorm.
In Arizona, dogs in Pima, Pinal, and Maricopa counties are more likely to be diagnosed with Valley Fever, with 6-10% of them contracting the disease every year.
Dogs frequently disturb and sniff dirt in their daily activities, which may contribute to the high incidence of Valley Fever in these areas.
How to Prevent
To prevent Valley Fever in dogs, keep them indoors as much as possible and walk them on paved sidewalks when outside. This will reduce their exposure to soils and airborne dust.
If you live in an area where Valley Fever is common, consider taking extra precautions to protect your dog's health.
Dogs can develop leptospirosis by coming into contact with wild animals or farm animals that may have the disease, or by drinking from contaminated water sources. This can happen even in your own backyard.
Exposure to rodents, such as squirrels or rats, and other dogs in areas like dog parks or facilities with multiple dogs can also increase your pet's risk.
Here are some ways to reduce your dog's risk of getting leptospirosis:
- Keep your dog on a leash when walking them
- Avoid letting your dog drink from streams, lakes, rivers, or puddles
- Prevent your dog from coming into contact with rodents or other dogs that may have the disease
Preventing leptospirosis is far more beneficial than treating it, as the disease can have severe consequences for your dog's kidney and liver function.
Symptoms and Diagnosis
Dogs in Arizona can be exposed to various diseases, and it's essential to recognize the symptoms and know how to diagnose them.
If your dog is exposed to Coccidiodes immitis, it may not show any symptoms, but if it does, typical symptoms include coughing, lethargy, fever, poor appetite, and weight loss.
In severe cases, the infection can spread outside of the lungs, causing additional symptoms such as back or neck pain, lameness, seizures, abscesses, and eye abnormalities.
If you suspect your dog has Valley Fever, it's crucial to tell your veterinarian about your dog's travel history and ask if a Valley Fever test should be administered.
Here is a list of symptoms for Valley Fever and Leptospirosis:
Veterinarians use a titer test to measure the level of antibodies against Coccidiodes within a blood sample, and combine the results with other diagnostic tests and a dog's symptoms and history to make the final determination as to whether or not a dog has Valley Fever.
Symptoms
Symptoms can be a real challenge to identify, especially if you're not sure what to look for. Coughing is a common symptom of Valley Fever in dogs, and it's often accompanied by lethargy, fever, poor appetite, and weight loss.
If left untreated, Valley Fever can lead to more serious symptoms like back or neck pain, lameness, seizures, and abscesses. In some cases, the infection can even spread to the eyes, heart, or other organs.
Some dogs may not show any symptoms at all, but if your furry friend is exposed to a large number of spores or has a weakened immune system, Valley Fever can take hold.
Here are some common symptoms of Valley Fever:
- Coughing
- Lethargy
- Fever
- Poor appetite
- Weight loss
- Back or neck pain
- Lameness
- Seizures
- Abscesses
- Skin wounds that don’t heal as expected
- Swollen lymph nodes
- Eye abnormalities
- Heart failure
- Blindness
Leptospirosis is another disease that can affect dogs, and it's characterized by symptoms like vomiting, shivering or fever, diarrhea, jaundice, and increased drinking and/or urination. If you notice any of these symptoms, it's essential to seek veterinary care right away.

Pet skin allergies can also be a problem, and they often manifest as scratching, licking, chewing or biting the skin, feet, and ears. Red, raised, scaly areas on the skin, bumps, crusts or pus-filled vesicles, and increased skin pigmentation are all common symptoms of skin allergies.
Here are some common symptoms of pet skin allergies:
- Scratching, licking, chewing or biting the skin, feet, and ears
- Red, raised, scaly areas on the skin
- Bumps, crusts or pus-filled vesicles on the skin
- Increased skin pigmentation
- Thickened skin
- Loss of hair
- Salivary staining (brown color)
- Head shaking
Diagnosing
Diagnosing Valley Fever in dogs requires a combination of symptoms, history, and test results. If you've recently traveled to an area where Valley Fever is common, tell your vet about your dog's travel history.
A titer test is the most common way to test for Valley Fever. This test measures the level of antibodies against Coccidiodes in a blood sample.
Veterinarians consider a dog's symptoms, history, and titer test results when making a diagnosis. They may also use other diagnostic tests like complete blood cell counts and X-rays.
Your veterinarian will need to know about your dog's travel history if you've recently moved from an area where Valley Fever is common.
